25 [0012] Se ha representado, en la figura 1, un dispositivo de amortiguacion 10, destinado a estar dispuesto[0012] A damping device 10, intended to be arranged, is shown in FIG.
detras de un dispositivo de acoplamiento 14 de un vehlculo ferroviario, y destinado a amortiguar un choque en una primera direccion, denominada direccion longitudinal X.behind a coupling device 14 of a railway vehicle, and intended to dampen a crash in a first direction, called longitudinal direction X.
[0013] Dicho dispositivo de acoplamiento 14, se representa mas en detalle en las figuras 3 a 5. Este 30 dispositivo de acoplamiento 14 consta de un primer organo 14A, destinado a estar conectado al dispositivo de[0013] Said coupling device 14, is shown in more detail in Figures 3 to 5. This coupling device 14 consists of a first organ 14A, intended to be connected to the device of
amortiguacion 10 de un primer vehlculo ferroviario y de un segundo organo 14B conectado a un segundo vehlculo ferroviario.damping 10 of a first railway vehicle and a second organ 14B connected to a second railway vehicle.
[0014] Mas particularmente, el dispositivo de acoplamiento 14 consta de una base plana de fijacion 14A, que 35 forma dicho primer organo y un larguero 14B, que forme dicho segundo organo, solidario a la base plana 14A, y que[0014] More particularly, the coupling device 14 consists of a flat fixing base 14A, which forms said first organ and a beam 14B, which forms said second organ, integral with the flat base 14A, and which
se extiende desde esta base plana 14A en la direccion longitudinal X. El larguero 14B presenta por ejemplo una forma general cillndrica.it extends from this flat base 14A in the longitudinal direction X. The beam 14B has for example a general cylindrical shape.
[0015] El dispositivo de amortiguacion 10 consta de una plaquita central 12, destinada a ser solidarizada a la 40 base plana de fijacion 14A del dispositivo de acoplamiento, como se representa en la figura 3. A tal efecto, la[0015] The damping device 10 consists of a central insert 12, intended to be joined to the flat fixing base 14A of the coupling device, as shown in Figure 3. For this purpose, the
plaquita central 12 consta por ejemplo de unos orificios 16 de fijacion de la base plana de fijacion 14A.central plate 12 consists for example of fixing holes 16 of the flat fixing base 14A.
[0016] El dispositivo de amortiguacion 10 consta ademas de dos alas laterales 18, formada cada una por una placa delgada, que se extiende en un plano paralelo a la direccion longitudinal X y a una segunda direccion Z,[0016] The damping device 10 also comprises two lateral wings 18, each formed by a thin plate, which extends in a plane parallel to the longitudinal direction X and a second direction Z,
45 denominada direccion vertical, perpendicular a la direccion longitudinal X. Asl, las alas laterales 18 se extienden esencialmente perpendicularmente a la plaquita central 12 y paralelamente una con respecto a otra.45 called the vertical direction, perpendicular to the longitudinal direction X. Thus, the lateral wings 18 extend essentially perpendicularly to the central insert 12 and parallel to each other.
[0017] Cada ala lateral 18 se denomina «delgada», debido a que su espesor, en una tercera direccion, denominada direccion transversal Y, perpendicular a la direccion longitudinal X y a la direccion vertical Z, es muy[0017] Each side wing 18 is called "thin", because its thickness, in a third direction, called the transverse direction Y, perpendicular to the longitudinal direction X and the vertical direction Z, is very
50 inferior a su longitud, en la direccion longitudinal X y a su altura en la direccion vertical Z.50 less than its length, in the longitudinal direction X and its height in the vertical direction Z.
[0018] De manera ventajosa, las alas laterales 18 son simetricas una con respecto a otra, con respecto a un plano central paralelo a la direccion longitudinal X y a la direccion vertical Z, estando este plano central definido como que pasa por el centro de la plaquita central 12, estando este centro definido en la direccion transversal Y.[0018] Advantageously, the lateral wings 18 are symmetrical with respect to each other, with respect to a central plane parallel to the longitudinal direction X and the vertical direction Z, this central plane being defined as passing through the center of the central insert 12, this center being defined in the transverse direction Y.
5555
[0019] Cada ala lateral 18 consta al menos de una primera region longitudinal 20, solidaria a la plaquita central 12 y al menos una segunda region longitudinal 22, asl como, entre cada primera region longitudinal 20 y cada segunda region longitudinal 22, una llnea de menor resistencia 24 respectiva, que separa esta primera 20 y segunda 22 regiones y que se extiende sobre el ala lateral 18 en la direccion longitudinal X. La primera region longitudinal 20[0019] Each lateral wing 18 consists of at least a first longitudinal region 20, integral with the central insert 12 and at least a second longitudinal region 22, as well as, between each first longitudinal region 20 and each second longitudinal region 22, a line of respective lower resistance 24, which separates this first 20 and second 22 regions and which extends over the lateral wing 18 in the longitudinal direction X. The first longitudinal region 20
se llama igualmente «region deformable» y cada segunda region longitudinal 22 se llama igualmente «region de fijacion».It is also called "deformable region" and each second longitudinal region 22 is also called "fixation region".
[0020] Cada segunda region longitudinal 22 esta destinada a ser solidarizada a dicho primer vehlculo 5 ferroviario (no representado).[0020] Each second longitudinal region 22 is intended to be in solidarity with said first railway vehicle 5 (not shown).
[0021] En el ejemplo representado, cada ala lateral 18 consta de dos segundas regiones longitudinales 22, a[0021] In the example shown, each side wing 18 consists of two second longitudinal regions 22, a
saber una segunda region longitudinal superior y segunda longitudinal inferior, dispuesta a ambos lados de la primera region longitudinal 20 en la direccion vertical Z.knowing a second upper longitudinal region and a second lower longitudinal region, arranged on both sides of the first longitudinal region 20 in the vertical direction Z.
1010
[0022] Asl, la segunda region longitudinal superior esta separada de la primera region longitudinal 20 por una llnea de menor resistencia superior, y la segunda region longitudinal inferior esta separada de la primera region longitudinal 20 por una llnea de menor resistencia inferior. Estas llneas de menor resistencia superior e inferior 24 se extienden, por ejemplo, paralelamente una con respecto a otra, en la direccion longitudinal X.[0022] Thus, the second upper longitudinal region is separated from the first longitudinal region 20 by a line of lower upper resistance, and the second lower longitudinal region is separated from the first longitudinal region 20 by a line of lower lower resistance. These lines of lower upper and lower resistance 24 extend, for example, parallel to one another, in the longitudinal direction X.
15fifteen
[0023] De manera ventajosa, cada segunda region longitudinal 22 de cada ala lateral 18 consta de una[0023] Advantageously, each second longitudinal region 22 of each lateral wing 18 consists of a
primera parte 26 (igualmente llamada parte delantera), dispuesta de un primer lado de la plaquita central 12 en la direccion longitudinal X y una segunda parte 28 (igualmente llamada parte trasera), dispuesta de un segundo lado de la plaquita central 12 en la direccion longitudinal X. Esta segunda parte 28 esta dispuesta del mismo lado de lafirst part 26 (also called the front part), disposed of a first side of the central insert 12 in the longitudinal direction X and a second part 28 (also called the rear part), disposed of a second side of the central insert 12 in the direction longitudinal X. This second part 28 is arranged on the same side of the
20 plaquita central 12 que la primera region longitudinal 20.20 central insert 12 than the first longitudinal region 20.
[0024] Dicho primer vehlculo ferroviario esta destinado entonces a estar incorporado a la primera parte 26 de cada segunda region longitudinal 22. Tal conexion por la primera parte 26 del dispositivo de amortiguacion 10, simplifica el desmontaje y el nuevo montaje de este dispositivo de amortiguacion 10, especialmente en el caso de[0024] Said first railway vehicle is then intended to be incorporated into the first part 26 of each second longitudinal region 22. Such connection by the first part 26 of the damping device 10 simplifies the disassembly and reassembly of this damping device. 10, especially in the case of
25 una colision que provoca su deformacion, es decir el desplazamiento de la plaquita central 12 entre las alas 18.25 a collision that causes its deformation, that is to say the displacement of the central insert 12 between the wings 18.
[0025] Conforme a una variante de realizacion no representada, las alas laterales 18 estan integradas en el chasis del vehlculo ferroviario. Asl, en este ejemplo, el dispositivo de amortiguacion 10 forma parte integrante del chasis del vehlculo ferroviario.[0025] According to a variant embodiment not shown, the lateral wings 18 are integrated in the chassis of the railway vehicle. Thus, in this example, the damping device 10 forms an integral part of the chassis of the railway vehicle.
3030
[0026] De manera ventajosa, la plaquita central 12 presenta una altura, en la direccion vertical Z, esencialmente igual a una altura de la primera region 20 de cada ala lateral 18 en esta misma direccion vertical Z. Asl, las llneas de menor resistencia superior e inferior 24 se situan respectivamente en la prolongacion de un borde superior 12A e inferior 12B de la plaquita central 12.[0026] Advantageously, the central insert 12 has a height, in the vertical direction Z, essentially equal to a height of the first region 20 of each lateral wing 18 in this same vertical direction Z. Asl, the lines of least resistance upper and lower 24 are respectively located in the extension of an upper and lower edge 12A and 12B of the central insert 12.
3535
[0027] De manera ventajosa, el dispositivo de amortiguacion 10 consta de una hoja de metal, recortada y legada de manera que forme la plaquita central 12 y las alas laterales 18. Esta hoja de metal esta representada, antes del legado, en la figura 2. Aparece claramente que tal hoja de metal presenta una estructura simple, de modo que su realizacion es simple y economica.[0027] Advantageously, the damping device 10 consists of a metal sheet, cut and bent so as to form the central insert 12 and the lateral wings 18. This metal sheet is represented, before the legacy, in the figure 2. It clearly appears that such a sheet of metal has a simple structure, so that its realization is simple and economical.
4040
[0028] Asl, un procedimiento de fabricacion del dispositivo de amortiguacion 10 consta de una etapa de corte de una hoja de metal para darle la forma de la representada en la figura 2, seguido de una etapa de trazado de ranuras para formar las llneas de menor resistencia 24 y una etapa de plegado de la hoja, plegando las alas laterales de 18 a 90° de la plaquita central 12, para delimitar esta plaquita central 12 y estas alas laterales 18.[0028] Thus, a manufacturing method of the damping device 10 consists of a step of cutting a sheet of metal to give it the shape of that shown in Figure 2, followed by a step of plotting grooves to form the lines of lower resistance 24 and a stage of folding of the leaf, folding the lateral wings of 18 to 90 ° of the central plate 12, to delimit this central plate 12 and these lateral wings 18.
45Four. Five
[0029] El dispositivo de acoplamiento 14 y el dispositivo de amortiguacion 10 tal como se ha descrito anteriormente se representan parcialmente en la figura 3.[0029] The coupling device 14 and the damping device 10 as described above are partially shown in Figure 3.
[0030] Como se ha indicado anteriormente, el dispositivo de acoplamiento 14 esta incorporado a la plaquita 50 central 12, por medio de la base plana de fijacion 14A en contacto con esta plaquita central 12.[0030] As indicated above, the coupling device 14 is incorporated into the central insert 50, by means of the flat fixing base 14A in contact with this central insert 12.
[0031] De manera ventajosa, la base plana 14A presenta una dimension, en la direccion transversal Y, que es inferior a la distancia entre las alas laterales 18 en esta misma direccion transversal Y. Asl, cualquier esfuerzo aplicado por la base plana 14A sobre la plaquita central 12 en la direccion longitudinal X esta dirigido hacia el[0031] Advantageously, the flat base 14A has a dimension, in the transverse direction Y, which is less than the distance between the lateral wings 18 in this same transverse direction Y. Thus, any effort applied by the flat base 14A on the central insert 12 in the longitudinal direction X is directed towards the
55 espacio delimitado entre las alas laterales 18. Se garantiza asl el desplazamiento de la plaquita central 12 entre las alas laterales 18 durante la deformacion del dispositivo de amortiguacion 10, como se va a describir mas abajo.55 enclosed space between the lateral wings 18. The displacement of the central insert 12 between the lateral wings 18 during deformation of the damping device 10 is guaranteed, as will be described below.
[0032] En caso de choque en la direccion longitudinal X, el dispositivo de acoplamiento 14 transmite un esfuerzo debido al impacto en la plaquita central 12, en la direccion longitudinal X, por medio del primer organo 14A.[0032] In the event of a shock in the longitudinal direction X, the coupling device 14 transmits an effort due to the impact on the central insert 12, in the longitudinal direction X, by means of the first organ 14A.
[0033] Estando la primera parte 26 de cada segunda region longitudinal 22 conectada a dicho primer vehlculo[0033] The first part 26 of each second longitudinal region 22 being connected to said first vehicle
ferroviario, el esfuerzo debido al impacto se concentra en los puntos de conexion entre la plaquita central 12 y las segundas regiones longitudinales 22.railway, the effort due to impact is concentrated at the connection points between the central insert 12 and the second longitudinal regions 22.
55
[0034] No obstante, las primeras partes 26 de estas segundas regiones longitudinales 22 estan dispuestas delante de la plaquita central 12, y las llneas de menor resistencia 24 se situan en la prolongation de los bordes superior 12A e inferior 12B de la plaquita central 12. Por tanto, dichos puntos de conexion forman unos comienzos para la rotura de las alas laterales 18 a lo largo de las llneas de menor resistencia 24.[0034] However, the first parts 26 of these second longitudinal regions 22 are arranged in front of the central insert 12, and the lines of least resistance 24 are located in the extension of the upper edges 12A and lower 12B of the central insert 12 Therefore, said connection points form beginnings for breaking the lateral wings 18 along the lines of least resistance 24.
1010
[0035] Asl, desplazando la plaquita central 12 en la direction longitudinal X, entre las alas laterales 18 y manteniendo las primeras partes 26 de las segundas regiones 22 de estas alas laterales 18 solidarias a dicho primer vehlculo ferroviario, se genera la rotura de las llneas de menor resistencia 24 que se situan en la prolongacion de los bordes superior 12A e inferior 12B de la plaquita central 12, asl como la deformation de las primeras regiones 20 de[0035] Asl, moving the central insert 12 in the longitudinal direction X, between the lateral wings 18 and maintaining the first parts 26 of the second regions 22 of these lateral wings 18 in solidarity with said first railway vehicle, the breakage of the lines of least resistance 24 that are located in the extension of the upper 12A and lower 12B edges of the central insert 12, as well as the deformation of the first regions 20 of
15 estas alas laterales 18, como se representa en la figura 4.15 these side wings 18, as shown in Figure 4.
[0036] Se observara que esta rotura se hace posible por el hecho de que las alas laterales 18 estan formadas por unas placas delgadas. El espesor de estas placas delgadas se escoge lo suficientemente reducido para permitir la rotura, pero lo suficientemente importante para que esta rotura necesite una energla relativamente importante.[0036] It will be noted that this breakage is made possible by the fact that the lateral wings 18 are formed by thin plates. The thickness of these thin plates is chosen small enough to allow breakage, but important enough that this break needs a relatively important energy.
20twenty
[0037] Esta energla necesaria para realizar las roturas de las alas laterales 18 y la deformacion de las regiones longitudinales 20, se extrae de la energla inicial del impacto. En otros terminos, se absorbe asl al menos una parte de la energla del impacto.[0037] This energy needed to make the lateral wing breaks 18 and the deformation of the longitudinal regions 20, is extracted from the initial impact energy. In other terms, at least part of the impact energy is absorbed.

Se garantiza asl que se deforman simetricamente una con respecto a la otra durante la absorcion del choque, de forma que esta absorcion del choque se distribuya equitativamente entre las dos alas laterales 18. Ademas, se garantiza igualmente asl el guiado del desplazamiento del primer organo 14A en la direccion longitudinal X.previously. It is thus guaranteed that they deform symmetrically with respect to each other during shock absorption, so that this shock absorption is distributed evenly between the two lateral wings 18. Furthermore, the guidance of the movement of the first organ 14A is also guaranteed. in the longitudinal direction X.
